Amazon CLF-C02 Online Questions & Answers

• Question 1041:

  A company wants to integrate natural language processing (NLP) into business intelligence (Bl) dashboards. The company wants to ask questions and receive answers with relevant visualizations.

  Which AWS service or tool will meet these requirements?

  A. Amazon Macie
  B. Amazon Rekognition
  C. Amazon QuickSight Q
  D. Amazon Lex
  C. Amazon QuickSight Q

  ---

  Explanation

  Amazon QuickSight Q is a natural language query feature that lets you ask questions about your data using everyday language and get answers in seconds. You can type questions such as "What are the total sales by region?" or "How did marketing campaign A perform?" and get answers in the form of relevant visualizations, such as charts or tables. You can also use Q to drill down into details, filter data, or perform calculations. Q uses machine learning to understand your data and your intent, and provides suggestions and feedback to help you refine your questions.

• Question 1042:

  A company wants to rightsize its Amazon EC2 instances.

  Which configuration change will meet this requirement with the LEAST operational overhead?

  A. Add EC2 instances in another Availability Zone.
  B. Change the size and type of the EC2 instances based on utilization.
  C. Convert the payment method from On-Demand to Savings Plans.
  D. Reprovision the EC2 instances with a larger instance type.
  B. Change the size and type of the EC2 instances based on utilization.

  ---

  Explanation

  Rightsizing involves adjusting instance types based on actual utilization to optimize costs and performance. Changing the size and type of EC2 instances according to utilization data achieves this with minimal operational overhead. Adding instances or changing payment methods does not directly address instance resizing, and reprovisioning with larger instances may not be optimal based on actual usage.

• Question 1043:

  A company is migrating to the AWS Cloud instead of running its infrastructure on premises. Which of the following are advantages of this migration? (Choose two.)

  A. Elimination of the need to perform security auditing
  B. Increased global reach and agility
  C. Ability to deploy globally in minutes
  D. Elimination of the cost of IT staff members
  E. Redundancy by default for all compute services
  B. Increased global reach and agility
  C. Ability to deploy globally in minutes

• Question 1044:

  Which AWS service or feature offers security for a VPC by acting as a firewall to control traffic in and out of subnets?

  A. AWS Security Hub
  B. Security groups
  C. Network ACL
  D. AWSWAF
  C. Network ACL

  ---

  Explanation

  A network access control list (network ACL) is a feature that acts as a firewall for controlling traffic in and out of one or more subnets in a virtual private cloud (VPC). AWS Security Hub is a service that provides a comprehensive view of the security posture of AWS accounts and resources. Security groups are features that act as firewalls for controlling traffic at the instance level. AWS WAF is a web application firewall that helps protect web applications from common web exploits.

• Question 1045:

  What does Amazon CloudFront provide?

  A. Automatic scaling for all resources to power an application from a single unified interface
  B. Secure delivery of data, videos, applications, and APIs to users globally with low latency
  C. Ability to directly manage traffic globally through a variety of routing types, including latency-based routing, geo DNS, geoproximity, and weighted round robin
  D. Automatic distribution of incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and AWS Lambda functions
  B. Secure delivery of data, videos, applications, and APIs to users globally with low latency

• Question 1046:

  A company is running a key-value NoSQL workload on Amazon EC2 instances. The company needs the workload to have scalability, failover protection, and backup capabilities.

  What is the MOST operationally efficient way to meet these requirements?

  A. Add additional EC2 instances to the database cluster.
  B. Run an identical copy of the database in a second Availability Zone.
  C. Migrate the database to Amazon DynamoDB.
  D. Migrate the database to a relational database.
  C. Migrate the database to Amazon DynamoDB.

• Question 1047:

  Which design principles should a company apply to AWS Cloud workloads to maximize sustainability and minimize environmental impact? (Select TWO.)

  A. Maximize utilization of Amazon EC2 instances.
  B. Minimize utilization of Amazon EC2 instances.
  C. Minimize usage of managed services.
  D. Force frequent application reinstallations by users.
  E. Reduce the need for users to reinstall applications.
  A. Maximize utilization of Amazon EC2 instances.
  E. Reduce the need for users to reinstall applications.

  ---

  Explanation

  To maximize sustainability and minimize environmental impact, a company should apply the following design principles to AWS Cloud workloads: maximize utilization of Amazon EC2 instances and reduce the need for users to reinstall applications. Maximizing utilization of Amazon EC2 instances means that the company can optimize the performance and efficiency of their compute resources, and avoid wasting energy and money on idle or underutilized instances. The company can use features such as Amazon EC2 Auto Scaling, Amazon EC2 Spot Instances, and AWS Compute Optimizer to automatically adjust the number and type of instances based on demand, cost, and performance. Reducing the need for users to reinstall applications means that the company can minimize the amount of data and bandwidth required to deliver their applications to users, and avoid unnecessary downloads and updates that consume energy and resources. The company can use services such as Amazon CloudFront, AWS AppStream 2.0, and AWS Amplify to deliver their applications faster, more securely, and more efficiently to users across the globe. Minimizing utilization of Amazon EC2 instances, minimizing usage of managed services, and forcing frequent application reinstallations by users are not design principles that would maximize sustainability and minimize environmental impact. Minimizing utilization of Amazon EC2 instances would reduce the performance and efficiency of the compute resources, and potentially increase the costs and complexity of the cloud workloads. Minimizing usage of managed services would increase the operational overhead and responsibility of the company, and potentially expose them to more security and reliability risks. Forcing frequent application reinstallations by users would increase the amount of data and bandwidth required to deliver the applications to users, and potentially degrade the user experience and satisfaction.

• Question 1048:

  A company wants to know more about the benefits offered by cloud computing. The company wants to understand the operational advantage of agility. How does AWS provide agility for users?

  A. The ability the ensure high availability by deploying workloads to multiple regions
  B. A pay-as-you-go model for many services and resources
  C. The ability to transfer infrastructure management to the AWS Cloud
  D. The ability to provision and deprovision resources quickly with minimal effort
  D. The ability to provision and deprovision resources quickly with minimal effort
